This association includes dry-mesic forests dominated by varying proportions of <i>Quercus muehlenbergii</i> and <i>Quercus shumardii</i>. It occurs in the Interior Low Plateau of Alabama, Kentucky and Tennessee, and also extends into the Ridge and Valley and Cumberland Plateau of Alabama and Georgia, on soils derived from limestones or other basic substrates, on gently rolling to rolling topography or on upper to mid slopes. In addition to the nominal species, the canopy may also contain some mixture of <i>Acer saccharum, Carya glabra, Fraxinus americana, Fraxinus quadrangulata</i>, and <i>Ulmus serotina</i>. Particularly towards the southern portion of the association's distribution, <i>Carya carolinae-septentrionalis</i> joins or replaces <i>Carya ovata</i> as the predominant hickory. Subcanopy species include <i>Quercus stellata, Aesculus glabra, Gleditsia triacanthos, Juniperus virginiana var. virginiana, Ulmus alata, Ulmus americana, Ulmus serotina</i> (to the south), <i>Ulmus thomasii</i> (to the north), <i>Cercis canadensis var. canadensis, Celtis laevigata var. laevigata, Ostrya virginiana, Fraxinus quadrangulata, Prunus mexicana</i>, and <i>Juglans nigra</i>. Shrubs include <i>Forestiera ligustrina, Frangula caroliniana, Hypericum frondosum, Rhus aromatica var. aromatica, Sideroxylon lycioides, Symphoricarpos orbiculatus</i>, and <i>Viburnum rufidulum</i>. <i>Bignonia capreolata</i> is a prominent liana. Other woody vines include <i>Lonicera sempervirens</i> and <i>Parthenocissus quinquefolia</i>. Herbs, a mixture of submesic and xeric limestone species, include <i>Fleischmannia incarnata, Lithospermum tuberosum, Polygonatum biflorum, Polymnia canadensis, Scutellaria ovata, Sedum pulchellum, Packera anonyma (= Senecio anonymus), Tragia cordata, Ruellia humilis, Ruellia strepens, Matelea gonocarpos, Arabis laevigata var. laevigata, Cuphea viscosissima, Galium</i> sp., <i>Diarrhena americana (= var. americana), Elymus</i> sp., <i>Senna marilandica (= Cassia marilandica), Chimaphila maculata, Salvia urticifolia, Tiarella cordifolia, Triosteum angustifolium, Asplenium platyneuron</i>, and <i>Asplenium resiliens</i>. Examples of this association may grade into ~<i>Juniperus virginiana</i> var. <i>virginiana - Fraxinus quadrangulata / Polymnia canadensis - (Astranthium integrifolium)</i> Woodland (CEGL003754)$$, ~<i>Quercus alba - Quercus rubra - Quercus muehlenbergii / Cercis canadensis</i> Forest (CEGL002070)$$, or ~<i>Quercus muehlenbergii - Quercus (falcata, shumardii, stellata) / Cercis canadensis / Viburnum rufidulum</i> Forest (CEGL007699)$$. Most examples observed seem to be generally subxeric. More mesic examples, formerly regarded as a 'mesic variant' of this association, are now accommodated as ~<i>Quercus shumardii - Quercus muehlenbergii - Acer (barbatum, leucoderme, saccharum) / Ostrya virginiana</i> Forest (CEGL008442)$$. |

This upland subxeric woodland community was a matrix forest type in the Ouachita Mountains and, historically, north into parts of the Ozarks. This community occurs on a variety of sandstone and mixed sandstone/shale-derived substrates in the northern and western Ouachita Mountains and on chert/novaculite-derived substrates in the central Ouachitas. On the sharper ridges of the central Ouachitas (novaculite uplift), these woodlands are reduced in extent and bounded by submesic pine - oak forest on lower slopes and xeric oak woodlands on the ridgelines. This is a fire-maintained community where woody succession and canopy closure can be rapid with fire suppression. Virtually extirpated, these woodlands have been restored in part by thinning and prescribed burning. This woodland community has an open canopy dominated by <i>Pinus echinata</i> and a dense, diverse herbaceous layer. Scattered oaks (<i>Quercus alba, Quercus stellata, Quercus velutina, Quercus marilandica</i>) may appear in the canopy or subcanopy. These are expansive, open woodlands on gentle slopes, saddles and flatter ridgelines in eastern Oklahoma, western Arkansas, and southern Missouri. The dense herbaceous stratum is dominated by both graminoid and forb species. Dominant graminoids include <i>Schizachyrium scoparium, Danthonia spicata, Chasmanthium sessiliflorum, Scleria triglomerata</i>, and <i>Dichanthelium</i> spp. Other graminoid species include <i>Andropogon gyrans, Andropogon gerardii, Andropogon virginicus, Chasmanthium latifolium, Gymnopogon ambiguus, Muhlenbergia schreberi, Panicum virgatum, Paspalum</i> sp., <i>Sorghastrum nutans, Sporobolus compositus (= Sporobolus asper)</i>, and <i>Tridens flavus</i>. Dominant forb species include <i>Solidago ulmifolia, Clitoria mariana, Lespedeza repens, Antennaria plantaginifolia, Symphyotrichum anomalum (= Aster anomalus), Symphyotrichum patens (= Aster patens), Erechtites hieraciifolia, Helianthus hirsutus</i>, and <i>Monarda russeliana</i>. Many other forb species are known from these woodlands. Some of the more typical ones include <i>Acalypha virginica, Amphicarpaea bracteata, Baptisia nuttalliana, Chamaecrista fasciculata (= Cassia fasciculata), Coreopsis tinctoria, Conyza canadensis, Cunila origanoides, Dalea candida, Desmodium ciliare, Echinacea pallida, Echinacea purpurea, Euphorbia corollata, Pseudognaphalium obtusifolium (= Gnaphalium obtusifolium), Hieracium gronovii, Lespedeza</i> spp., <i>Liatris squarrosa, Phlox</i> spp., <i>Polygala alba, Pycnanthemum tenuifolium, Rudbeckia hirta, Solidago hispida, Solidago odora, Solidago radula, Stylosanthes biflora</i>, and <i>Tephrosia virginiana</i>. Shrubs are sparse, especially in more frequently burned locations. Shrub density is related to fire frequency, and many shrubs are coppices, sprouting from stumps. Some common shrubs and vines include <i>Baptisia bracteata var. leucophaea, Carya alba, Carya texana, Ceanothus</i> spp., <i>Crataegus crus-galli, Mimosa microphylla, Prunus serotina, Quercus stellata, Rhus copallinum, Rhus glabra, Rubus</i> spp., <i>Toxicodendron radicans, Ulmus alata, Vaccinium arboreum, Vaccinium pallidum, Viburnum rufidulum</i>, and <i>Vitis rotundifolia</i>, but many others can occur. The type location is in Scott County, Arkansas. |

This community occurs on moist, vertical, mostly north-facing sandstone cliffs and bluff-lines on Mount Magazine, Arkansas, and probably elsewhere. Ledges support dense mats of <i>Deschampsia flexuosa</i>. Other common and characteristic species include <i>Dennstaedtia punctilobula, Dryopteris marginalis, Heuchera americana var. hirsuticaulis, Hydrangea arborescens, Ribes cynosbati, Parthenocissus quinquefolia</i>, and <i>Asplenium bradleyi</i>. Trees present at the summits of the cliffs include <i>Quercus acerifolia</i> and <i>Quercus marilandica var. ashei</i>. |
